From 2bc1c59dbdefdb6f9767e06efb86bbdb2923a8be Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 5 Nov 2009 11:18:09 -0600 Subject: [SCSI] fc class: fail fast bsg requests If the port state is blocked and the fast io fail tmo has fired then this patch will fail bsg requests immediately. This is needed if userspace is sending IOs to test the transport like with fcping, so it will not have to wait for the dev loss tmo. With this patch he bsg req fast io fail code behaves like the normal and sg io/passthrough fast io fail.
